| ==About the Nanode - Some Background==
| | Thankyou for your support. Team Nanode. |
|
| |
|
| The Nanode is a low cost entry device aimed at Internet Connectivity projects. It has been designed to be built easily for under £20 - so that it will appeal to those on a tight budget.
| | ==A 30 second pitch== |
| | Nanode is an open source Arduino-like board that has in-built web connectivity. It connects to a range of wireless, wired and ethernet interfaces. |
| | It allows you to develop web based sensor and control systems - giving you web access to six analogue sensor lines and six digital I/O lines. |
| | It costs under £20 as an easy build it yourself kit. Nanode was designed with Hacking in mind. |
|
| |
|
| It is based on the Arduino environment so will be familiar to many. It will accept Arduino shields, if necessary with longer pins to improve clearance between the Magjack connector and the underside of the shield.
| | ==How to get one?== |
| | Here is a [http://shop.nanode.eu list of websites] where you can purchase a Nanode kit. |
|
| |
|
| It consists of a small PCB which has the ATmega328 microcontroller, some glue logic, the ENC28J60 ethernet controller and a Magjack ethernet connector. The board only uses through-hole and DIL conventional components - so that it can be easily assembled by anyone who has basic solderng skills.
| | ==What can you do with it?== |
| | Update to Pachube |
|
| |
|
| It makes an ideal project for a teaching workshop on web connectivity, and as such will appeal to Hackspaces for advanced Arduino workshops.
| | Anything you can do with an Arduino, and an Arduino+Ethernet shield |

|
| Another unique feature is that several Nanodes can be connected together on a multidrop serial bus and used for distributed control tasks, such as energy montoring or home automation. The wired network supplies communications and power and can be made from low cost 4 core telephone cable. Individual Nanodes can communicate via this network back to an ethernet connected "Master" unit. With RS485 driver ICs, the Nanode can be adapted as a DMX lighting controller, MIDI network or other serial control system.

|
| [[User:Monsonite|Ken]] I will be hosting a Nanode build session at the space on Saturday 2nd April from 10am. | | Ian Chilton has started to maintain a page of [http://ichilton.github.com/nanode useful Nanode links], including pointers to [http://github.com/ichilton/nanode code] and libraries for the various functions of the Nanode and Nanode RF. |
|
| |
|
| There will be the opportunity to build up 2 pairs of Nanodes and get them talkng to each other via Pachube. There will be 4 Nanodes available for the Pachube Hackathon, with priority given to LHS members. Even if you are not at the event, but want to play with the Nanode at the space, during that event, let me know.
| | ==What we need help with== |
| | Sorting out the vast amounts of info that have been dumped here. |
|
| |
|
| ==Board waiting list==
| | The idea is to have lots of project pages with the Project:Nanode namespace. Each project page would have a bunch of info+links. The intention is to make them into 'chapters' that people can refer to, or download. Most content resides in [[Project:Nanode/scratch]]. It just needs splitting up. |
| [[User:Teabot|Elliot]] has started a [http://wiki.hackspace.org.uk/wiki/Pledges/Nanodes Pledge Page] so that we can pool component purchasing and get the best price. The cost is £18 per Nanode which is a full kit of parts including pcb.
| |
|
| |
|
| I would like to do a special London Hackspace branded version with a custom LHS logo on the screenprint. If anyone with EagleCAD experience would like to assist with this artwork please get in touch. As soon as we have this artwork and a minor board update, we can order the next batch. --[[User:Monsonite|Ken]]
| | [[Category:Projects]] |
| | |
| Now that we have reached 30 boards, we should consider collecting some money and getting a batch of pcbs ordered from Spirit Electronics. I think that 2 square feet of board will just about fit 40 boards. --[[User:Monsonite|Ken]]
| |
| | |
| ==The First Prototypes==
| |
| | |
| Here are the two boards each connected to a network port. The orange and brown wires between the boards is so that they can share the 5V power from the FTDI cable.
| |
| | |
| [[File:Putter_Getter.jpg|320px|center|thumb|Putter and Getter Nanodes]]
| |
| | |
| The upper board is the Publisher (Putter) and the lower board is the Subscriber (Getter). Every few seconds the Putter sends a new packet of data up to Pachube feed 8729, and at regular intervals the Getter subscribes to this feed to retrieve the data. In this case the data is a simple comma separated list of 6 arguments, which could be six readings from the ADCs on the Putter device, or a numerical command to which the Getter will respond.

| | |
| ==Nanode: Applications and Brainstorming==
| |
| | |
| This section is for all potential applications and wild ideas of what can be done with the Nanode.
| |
| | |
| As a simple example, a Nanode could read up to 6 analogue sensors, connected to its ADC inputs - such as temperature sensing thermistors or LM35 thermometer ICs. These temperature sensors are located in different rooms of the house, or outside, or on the hot water tank. Between them they give an indication of the state of the home heating. The temperature readings are published up to a Pachube feed, where they can be accessed by other devices. A Nanode subscribing to the feed reads the temperature data as a CSV string, strips out the numerical data and acts on its content. For example controlling a user display, operating relays which control the boiler for heating or hot water as it is required.
| |
| | |
| The CSV format which Pachube uses is flexible enough to cope with many types of data, or even direct numerical commands. A string of comma separated, numerical commands passed up to Pachube could be simply interpreted by any subscribing Nanodes to perform a specific action. The first number could be the address of the Nanode which you want to command, for example the one which controls the boiler relay.
| |
| | |
| [http://openenergymonitor.org/emon/ Openenergymonitor] have developed some very low cost Arduino based devices to read electricity and gas meters. One of these will shortly be released as an Arduino shield and could use the Nanode as its connection to the net.
| |
| | |
| The other main application of the Nanode is in Master/Slave wired networks. Several Nanodes are connected to a wired serial bus and distributed about the environment where they run sensing or control tasks - such as a home automation system or DMX lighting control system. Each slave can be addressed individually by a Master controller, which then connects via its ethernet connection to the web.
| |
| | |
| Slaves could store sensor readings in RAM (limited to 2K on the '328) and periodically be polled by the Master device to connect to the serial bus and upload its data. Data could be recorded straight off the serial bus using the [http://www.sparkfun.com/products/9530 Openlog] serial data logger concept from Sparkfun Electronics. The Openlog code runs nicely on an Arduino fitted with a SDcard shield, so could be run on the Master Nanode. The Master could act as a SDcard based file server or storage to the serially connected slaves.
| |
| | |
| ==Questions & Answers & Feedback==
| |
| | |
| If you have any queries - please put them here.
| |
| | |
| Is the local bandwidth between two nanodes enough to create an ethernet bridge in software? -- Answer to myself: the multidrop bus is in the range of 9600 baud.
| |
| | |
| The ATmega328 is not limited to 9600 baud serial. If the distance between nodes is short then 115,200baud may be possible. You could also connect nodes together with I2C or SPI. [[User:Monsonite|Ken]]
| |
| | |
| Can non-members join the PCB batch?
| |
| | |
| Yes - but note that we are currently only offering a full kit consisting of pcb and all components.
| |
|
| |
| > Thanks. And the same deal in joining in with the full parts order? (£18.00+donation). Do we just add names to the list above?
| |
| | |
| We have been looking at the practicalities of providing a full kit, and think this is the best way to proceed, at this time.
| |
| | |
| Bare boards may be available at a later date, but for now the £18 kit is the only option being offered. A small donation to the Hackspace from non-members would be appreciated. [[User:Monsonite|Ken]]
